pursuing a career in science. >> it was a completely ridiculous idea because there was no hope whatsoever of my doing science and then a time spent on it would be a total waste on my part and whoever had to teach me. but the nobel jury beg to differ. >> we now knew that -- know that development is not strictly a one-way street. >> there is hope that their work will pave the way for developing methods to diagnose and treat many diseases. >> to find out more about this, we are joined by our science correspondent. a lot of people around the world are working in stem cell research. why did these two get the prize? >> they got it for the same reason a lot of nobel prize laureates have gotten it -- they went against the currents. we used to believe that cell differentiation only went in one direction. you had these undifferentiated cells, stem cells, and then they became something in the course of development. in the embryo has a lot of them and they turn into bone, skin, liver. everyone thought it only went in one direction. this was the first time anyone was ever able to reverse it. he claime

generation. >> this trillion institution of marine science says the pace of damages kicking up. cyclones of predatory starfish are the main causes along with: gas shipments and global warming. >> coral reefs provide the breeding ground for countless species of fish. the great barrier reef is no exception. commercial fishing is now mostly banned across much of the area. three 6 cents more than 2,600 kilometers along the us trillion coast. the northern part of the refinements largely intact. it is the southern part scientists are worried about. severe storms are said to have cost nearly 50 percent -- said to have caused nearly 50% of the damage. a further 40% was caused by starfish that feed on the coral. one species, the crown of thorns, has proven especially deadly for the coral cover. >> we believe if we can take action on one of the things we can directly control, the crown of thorns starfish, it may leave the reef in a position where it can better withstand some of the climatic impact spite cyclone and coral bleaching. >> regardless of what is causing the damage, brain biolo

railroad. but us start the national academy of sciences. let us start colleges. because we want to give the gateways of -- date was of opportunities for all americans. all americans are getting opportunities, that enhances people's freedom. what i have tried to do as president is to apply those same principles. >> that is president obama from the debate this week on the role of government. let us listen to his challenger mitt romney with his answer. and then we will begin listening to you.

years of english, three years of science, math, and social science, compared to those who didn't complete a core curriculum, those who completed the core curriculum scored 144 points higher than those who did not. when we look at those who took honors courses, they scored nearly 300 points above those who did not take honors or ap courses. rigor of the academic course load in high school leads to do better on the s.a.t. and leads students to being better prepared for college. let me give you this information in terms of framing the challenge of our country faces. for every 100 ninth graders, only 70 will graduate from high school. 44 local want to college. only 30 students will enroll in the second year of college. only 21 will graduate from a four-year institution in a six- year period of time. that is not good enough to keep the united states competitive in a global economy. we are very much focused on having high expectations for all students and doing what we can to better prepare students for college success and keep those high expectations for all students coming from all d

, a political science professor at columbia university. good morning and thanks for being with us. >> thanks for having me. >> where do debates fit in? how important is it? guest: the base can play an important role. they probably take second place to conventions. they play a much greater role in changing people's minds. they probably play a lesser role when people are finally making up their minds. also, very early in the election year, when voters are just learning, there is a lot of volatility. the debate divides the time line. there are changes in the polls the only slightly greater than normally. host: there is a story from "the wall street journal" what do viewers and listeners look for? as they watch a debate text are looking for their candidate to in or aod zinger stumble? guest: 12% might be persuaded all but the other 88% are just watching. after the debate tonight, we will have many speculating on who won the debate and who lost the debate. in terms of voter preference, and in -- not a great deal will change. host: c-span is at the university of denver for the first pre

science academy's research center. his area of study is the northeast industrial region. there are over 1,000 factories in the tiexi industrial ne, which spreads along the west side of shenyang. many state-owned enterprises have factories here. they are typical of those that made up the backbone of the sialist economy. ( speaking chinese ) translator: one of the problems facing the tiexi industrial zone at the present time is the aging of its plants and uipment. quite a lot of it is old and is still in use after more than 20 years. actually, some of this equipment has been used for more than 30 years. the second problem ithat most of the factories in the region make everything they need in-house. this inefficient use of resources has resulted in many factories operating in the red. narrator: the shenyang number one machine tool works in tiexi is one such operation. its long history goes back to 1935, when manchuria was occupied by japan. the japanese established the region as a base of manufacturing for export to japan. they built a railroad and factories. the shenyang number one m
